are Sphagnum Lindbergii, 8. ri/parium, and S. obtusion. These are dis- 

 cussed critically and at some length. 



A. J. Grout * publishes an illustrated note on L&ptobryum pyri/orme 

 with gemmae from a greenhouse in Miami University. It differs in 

 habit and appearance from the normal fruiting plant. 



E. J. Hill f discusses the little-known Fontiimlis Umbachii Cardot, 

 ;md gives a translation of the original description. He publishes notes 

 on the type-locality and two other stations in Illinois where he has 

 collected the species, adding critical notes on the peculiarities of the 

 individual specimens. 



Hepaticse of Alaska. :£ — A. W. Evans publishes a report on the 

 hepatic* of Alaska based on a large collection made in 1913 by the 

 Kelp Investigation Expedition of the United States Bureau of Boils. 

 Most of the specimens were collected by Prof. T. C. Frye, of the 

 University of Washington. Seventy species are enumerated, twenty of 

 which are new to Alaska, seven new to America, and three new to 

 science. Thirty-five other species have been recorded, making the 

 total flora 105 species. Evans gives a bibliography of the more 

 important papers, and a map and a list of the localities visited by the 

 Expedition. He describes the following new species — ■ Plar/iochila 

 alaskana, P. Fri/ei, Radula polyclada, and discusses sundry other species 

 critically. He discusses also the relationship of the flora to that of 

 other regions.

Dicranacese of New Zealand.§ — H. N. Dixon continues his studies 

 in the Bryology of New Zealand by giving a critical account of the 

 following genera of Dicranacese :-- Trematodon (4 species) ; Pleuri- 

 dium (5) ; P. lonyirostre is new and found in Otago ; Ditrichum (7) ; 

 Saelania (1) : Ceratodoa (1 species and a sub-species) ; Gheilothela 

 (1 species); Distichivm (1): Pseudodistichium (2); iSdigeria (1) ; 

 Blindia (3) ; DicraneUa (5) ; D. ivairarapensis is new and occurs in the 

 North Island ; Campylopodmm (2) ; Dicranoweisia (1). All the species 

 recorded for New Zealand are carefully sifted, and according to their 

 merits are accepted, corrected, reduced to synonyms, or rejected. The 

 genera Bruohia and Dichodontkim. are rejected for lack of confirmatory 

 evidence of their existence in New Zealand. Keys to the genera and 

 species are provided. 



Australasian Hepaticse. ||— F. Stephani and W. W. Watts publish 

 a list of " Hepaticae Australes " collected in Australia and Lord Howe 

 Island by the Rev. W. W. Watts, and in the New Hebrides by the Rev. 

 Dr. Gunn and others. Descriptions of many new species are supplied 

 by Stephani — forty-nine from Australia, twenty-seven from the New 

 Hebrides, and six from Lord Howe Island.
